WATER-PROOF COMPOSITION FOR PAPER.

SPECIFICATION forming part of Letters Patent No. 369,700, dated'September 13, 1887.

Application filed November 19, 1886. Serial No. 219,398. (No specimens.)

T0 aZZ whom it may concern:

Be it known that I, WILLIAM H. FAY, a citizen of the United States, residing in the city and county of Camden, State of New Jersey, have invented a new and useful Improvement in Paper, which improvement is fully set forth in the following specification.

The object of my invention is to produce a paper which is water and vermin proof,tough and durable, clean, and comparatively odorless.

In carrying out my invention I employ paper made preferably of Manila stock and immerse, saturate, or coat the same with a compurpose of rendering the leather water-proof, such being old and described and claimed in the patent to James Oluman, N0.166,748, of August 17, 1875; but in the composition therein used the quantity of tallow is greater than that of either the paraffine or the rosin, this being necessary to render the leather soft and flexible. Owing to the excess of'the rosin in the composition used by applicant a different chemical action is the result, the paper being rendered tough as well as stiff, Waterproof, and durable.

Having thus described my iuventiomwhatl claim as new, and desire to secure by Letters Patent, is

A composition for rendering paper waterproof, tough, stiff, and durable, consisting ofamixture of one hundred parts of rosin and forty each of tallow and paraffine, substantially as described.

WILLIAM H. FAY.
